Abstract
User experience (UX) encompasses the concepts of usability and affective engineering. It is a crucial factor in the design of mobile devices. However, it has been difficult to gain a common understanding of the design characteristics that suit the different personalities of individuals when using mobile device technology. Therefore, in this thesis, a novel design of a mobile UI-based on the personality nuances was proposed. It was argued that such design would stimulate information processing in according to learners‘ mental model in order to obtain an effective and satisfying learning experience with a mobile phone. A total of 87 undergraduate students (15 male, and 35 female) were participated in this study. Learners‘ design preferences (such as structure, navigation, layout, font style attributes, text size, buttons, colour, list, information density, support, and alignment) were collected in according to their personality nuances (extraversion, agreeableness, conscientiousness, neuroticism, and openness to experience). To classify the participants according to their personality, two unsupervised learning algorithms were invoked: clustering and association rule. They yielded two personality clusters, which we call the neuroticism and the extra-conscientiousness group. Then, a mobile device UI design was developed for each participant group based on their members‘ characteristics. To evaluate the participants‘ learning experience when using each mobile device UI design, an eye-tracking device was used to record their eye fixation duration, saccade amplitude, and average pupil diameter level and thus measure their attention, interaction, and cognitive load, respectively.
